我的Ubunto 14.04机器上装了Shiny，工作正常。我刚刚升级到16.04 LTS，现在它已经不再适用了。我重新安装了Shiny并按照here的说明进行操作，但无济于事。
我创建了一个名为shiny-apps的用户组，它对我的网络应用程序具有读写权限：
owner@shiny-smith:/srv/shiny-server$ ls -l
total 0
lrwxrwxrwx 1 owner shiny-apps 33 Jul 13 2015 DroughtNet -> /home/owner/Documents/DroughtNet/
lrwxrwxrwx 1 owner shiny-apps 38 Jul 13 2015 index.html -> /opt/shiny-server/samples/welcome.html
lrwxrwxrwx 1 owner shiny-apps 37 Jul 13 2015 sample-apps -> /opt/shiny-server/samples/sample-apps
并且两者都有光泽＆＃39;和＆＃39;所有者＆＃39;是闪亮应用程序组的成员：
owner@shiny-smith:/srv/shiny-server$ groups owner
owner : owner adm cdrom sudo dip plugdev lpadmin sambashare shiny-apps
owner@shiny-smith:/srv/shiny-server$ groups shiny
shiny : shiny shiny-apps
但是，检查闪亮服务器仍会显示权限错误：
owner@shiny-smith:~$ shiny-server

[2016-12-30 14:29:38.648] [INFO] shiny-server - Shutting down worker processes
如果我添加＆＃39;所有者＆＃39;闪亮的服务器配置，没有解决问题：
owner@shiny-smith:~$ sudo nano /etc/shiny-server/shiny-server.conf
owner@shiny-smith:~$ sudo systemctl restart shiny-server
owner@shiny-smith:~$ shiny-server

有人可以帮我找出问题所在吗？
